    Philips 32PFL3807H/12 repair, bass speaker sweating acid liquid?!

    This one is weird. CSI like.

    It gets to me because left half screen is intermittently flickering. After opening, I see that central bass speaker box is wet. First I assume an external leak, but I can't see any signs of water or anything already dry in back cover (outside nor inside). Also, there're no signs of liquid in PSU or MAIN board. Even more: only one face of the speaker box is wet. The half that touches the LCD panel is totaly dry.

    But problem is that this liquid has dripped through LVDS cable to T-CON connector, and from there it has flowed down to LCD panel long boards. There's some damage to T-CON LVDS connector, and at left LCD board FFC connector. Looks like this liquid is slightly corrosive, but not a lot (otherwise, I'd have been unrepairable). Aside of cleaning, I've had to resolder two pins at FFC connector.

    So I deduct that plastic from the bass speaker has "sweated" that liquid. If someone else finds out the same thing, please report. I don't know if it will keep leaking from now on.

    Do you have a picture?
    I assume no responsibility for any stupid suggestions I might post.

      No, and it’s already reassembled.
